Abstract
A phosphorus oxyhalide cross-linked hydroxypropyl cereal starch has a D.S. of hydroxypropyl of at least 0.1 and a pH 6.5 buffered salt CIV viscosity of 60-150 gm.-cm. after 10 mins., and of 80-150 gm.-cm. after 40 mins. and is made by cross-linking a hydroxypropyl cereal starch with a D.S. of at least 0.1 in granular form with a phosphorus oxyhalide (POCl3 and POBr3 specified). The method of CIV viscosity determination is given. The initial hydroxypropylated cereal starch is made by propylation of cereal starch using Pr2O in an alkaline (pH 9-13) suspension of dioxane or a polar solvent, or is made by known dry reaction techniques. The product is washed and cross-linked, using suitably 0.01-0.05 parts wt. of phosphorus oxyhalide per 100 parts wt. of the hydroxypropylated starch, which suitably has a D.S. in the range 0.11-0.30. The product has usefulness in the food industry.
